Title: Valve for fire suppression
Inventor: KOWALSKI SLAWOMIR
IPC: A62C3/00
Filed: 1986-01-17
Granted: 1991-04-30
Abstract: F.4099 VALVE FOR FIRE SUPPRESSION     ABSTRACT OF THE DISCLOSURE     The invention contemplates a quick-opening valve for release of pressurized gas to suppress a hydrocarbon or the like fire and/or explosion.  A piston or poppet-valve member is retained by mechanical-latch mechanism in its readiness con-dition, normally closing off pressurized liquified suppressant gas against release for fast discharge via a discharge port.  Latch release is via short low-friction, low-inertia direct action which is independent of the pressure differential across the valve member.

Title: Glyphosate-resistant plants
Inventor: SHAH DILIP M
IPC: A01H5/00
Filed: 1986-08-06
Granted: 1993-02-23
Abstract: 07-21(381)A GLYPHOSATE-RESISTANT PLANT CELLS Abstract of the Disclosure This invention involves a cloning or expression vector comprising a gene which encodes 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) polypeptide which, when expressed in a plant cell contains a chloroplast transit peptide which allows the polypeptide, or an enzymatically active portion thereof, to be transported from the cytoplasm of the plant cell into a chloroplast in the plant cell, and confers a substantial degree of glyphosate resistance upon the plant cell and plants regenerated therefrom. The EPSPS coding sequence may be ligated to a strong promoter, such as the 35S promoter from cauliflower mosaic virus, to create a chimeric gene. Such genes can be inserted into plant transformation vectors, and subsequently introduced into plant cells. Plant cells transformed using such genes and plants regenerated therefrom have been shown to exhibit a substantial degree of glyphosate resistance.

Title: Dispensing machine for tea
Inventor: LAYRE JOHN
IPC: A47J31/00
Filed: 1987-06-29
Granted: 1990-11-20
Abstract: DISPENSING MACHINE FOR TEA              ABSTRACT OF THE DISCLOSURE    The present invention relates to an apparatus for nonpressurized infusion brewing of a beverage, and especially tea brewed freshly from tea leaves, primarily adapted for use in vending machines.  The apparatus includes a novel brew assembly comprising a frame, a carriage reciprocable along the frame between a brew position and discharge position.  The carriage is driven between the brew position and discharge position by a motor driven crank pin mounted on a crank arm in which the crank pin is slidable in a transverse slot formed in the carriage.  The carriage carries a brew cavity having an open top and bottom with externally extending guide pins mounted on opposed side walls.  The brew cavity is mounted within the carriage and is normally biased towards a lower positon.  The brew cavity includes a stop member which abruptly abuts the carriage after the guide pins of the brew cavity are raised by inclined cam members to a maximum point where the guide members ride off the end of the cam members to cause the discharge of spent tea leaves or other solid infusible material by virtue of inertia and gravity.  The brew cavity guide members then pass under the inclined cam members back to the brew position where the cycle begins again.

Abstract: A process for treating metal comprises applying a positive DC potential to an ionic melt layer disposed on the surface of a liquid metal.  The application of this potential provides a plasma phase above the ionic melt layer and induces a flow of electrons from the liquid metal towards the plasma phase. The ionic melt layer is capable of being maintained in a liquid state when it is in contact with the liquid metal. The process can be used either to remove impurities from the liquid metal, to alloy the liquid metal by adding metal compounds in the ionic melt layer, to recover metals from waste, or to perform a combination of these functions.  An apparatus for treating liquid metals is also provided.

Grenzowski ABSTRACT OF THE DISCLOSURE           There is disclosed a cell culture apparatus particularly suitable for the culture of viable, shear sensitive cells, either grown in suspension or attached to a substrate such as microcarrier beads.  The apparatus comprises a cell culture compartment and a compensation chamber disposed thereabove and serving to maintain sterile conditions for the cell culture compartment operating in a zero-headspace mode.  The cell culture compartment com-prises a gas exchange tube connected to an outside source of gas and defining a downflow zone and a central upflow zone in the cell culture compartment.  An Archimedean screw-type auger is installed coaxially in the cell cul-ture compartment to provide a circulating flow of liquid therein.  The turbulence of the flow is reduced by the provision of an upper and lower flow guide surface.  The gas exchange tube is adapted to exchange gas from outside with the liquid inside the cell culture compartment both on its outer and on its inner surface thereby enhancing the efficiency of gas exchange.

Abstract: AN ACTIVE DYNAMIC MEMORY CELL          Abstract A dynamic memory cell comprises a storage transistor and an access transistor. The gate of the storage transistor is utilized as a storage capacitor electrode, and is connected to its source by a high resistance resistor. The drain of the storage transistor is connected to a source of electrical potential (e.g., Vcc). The access transistor connects the source of the storage transistor to a bit line. This arrangement multiplies the effective capacitance of tile gate storage capacitor, reducing the area required and hence making the structure more compact than a typical inactive (one transistor) DRAM cell. In a preferred embodiment, the resistor is formed to overlie the storage transistor, and the drain of the storage transistor is connected to Vcc by means of the sidewall of a trench formed in the semiconductor substrate.
